After adding this parrotfish to my 150-gallon reef tank, it has been very calm and active. It doesn’t bother corals or other fish. Only suitable for experienced aquarists, but worth the effort.

The fish looks beautiful with its greenish-blotched coloration. It’s peaceful and has adapted well to the tank. I’ve had to monitor water parameters closely, which is expected for expert-level care.

Great addition to a mature reef setup. It’s not aggressive and has been eating algae without issues. I’m happy with the color and behavior after a few months.
